OMRON’s IC Connectors Have Excellent

Reliability and Can Tolerate Momentary

Interruptions in Power.

• Round pins and 4-point (4-finger) contact construction with

contact entry holes that are large for easy insertion.

• IC lead contacts placed high for solid connections.

• A wide product range: open-frame, closed-frame, single-

row, carrier-type DIP terminals, wrap terminals, solder-

sleeve terminals, and low-profile DIP terminals.

• Conforms to UL standards (file no. E 103202) and CSA

standards (file no. LR 62678).
